This repository contains test and example programs for RISC-V ETISS. A minimal linker configuration and startup code as well as basic exception handling is provided in riscv_crt0. The file etiss-semihost.specs is used to instruct the linker to use riscv_crt0 as startup code, and substitute standard system calls by semihosting calls.
CMake is used to automatically generate appropriate linker scripts and ETISS ini configurations. The latter can directly be loaded by bare_etiss_processor.
- CMake >= 3.10
- A RISC-V gcc cross-compiler toolchain, installed to
<toolchain prefix> - ETISS with semihosting support, installed to
<etiss prefix> - This repository, cloned to
<etiss examples>
Starting in <etiss examples>, run the following commands:
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=rv32gc-toolchain.cmake -DRISCV_TOOLCHAIN_PREFIX=<toolchain prefix> -DCMAKE_INSTALL_PREFIX=../install ..
make install
rv32gc-toolchain.cmake can be substituted by rv64gc-toolchain.cmake if desired.
